Atlanta, Georgia (CNN) - Darren Turner insisted on going to war, even though the Army usually reserves desk jobs at home for new chaplains like him.

Turner was young and green, enthusiastic about taking God to the battlefield. The Army captain had learned that people in pain are often wide-open to inviting God into their lives.

Jesus always ran to crises. Turner was going to do the same.

He’d enrolled in seminary in 2004 at Regent University in Virginia, founded by evangelist Pat Robertson. And early in his spiritual journey, he was inspired by Christian writer John Eldredge, who suggests that American men have abandoned the stuff of heroic dreams, aided by a Christianity that tells them to be "nice guys."

God, says Eldredge, designed men to be daring, even dangerous.

Turner arrived in Iraq in May 2007 with the 1st Battalion, 30th Infantry Regiment amid a raging insurgency. His soldiers faced an invisible but lethal enemy in booby-trapped houses and roads laced with massive bombs.

Chaplain Turner’s war would unfold on many fronts. He would be a soldier on the battlefield. A counselor behind closed doors. He was a friend, even a father, to his men.

And when his 15-month tour was over, Turner returned home to face all the problems he had counseled his soldiers about: anger, depression, stress and – most important for him – preserving relationships with loved ones.

Nearly 4,500 American troops died in the Iraq war. More than 30,000 more were physically wounded. Countless others live with scars that can't be seen, like post-traumatic stress syndrome and traumatic brain injury. Many have struggled with regaining their lives at home.

At Falcon, the Army provided a morale phone that allowed soldiers to make free 15-minute calls home. But Turner knew it wasn't enough. He carried a cell phone in the left shoulder pocket of his uniform and whipped it out whenever a soldier signaled domestic distress at home.

"Call her," he would say. "Call her now and tell her you love her."

When they returned to Georgia in the summer of 2008, Turner told his soldiers that their families would be their cushion. He knew his men were suffering; that the ghosts of Iraq would haunt them, maybe for the rest of their lives.

What he did not know then was that he would not himself be immune to the same threats. He neglected to heed his own advice and his life floundered.

I’d spent many weeks with Turner in Iraq for a story in the Atlanta Journal-Constitution, but I didn't know about his troubles until I drove up to meet him and his wife, Heather, earlier this year at Fort Campbell, Kentucky.

On that rainy February day, Turner told me that he’d come back from Iraq and felt like the bomb defuser in the movie "The Hurt Locker," who goes into a grocery store and is overwhelmed by the mesmerizing variety of cereals.

It was a lot to process after having few choices in Iraq. Reverse culture shock.

"I wanted everything in there but I wasn't sure what to buy," Turner said.

He also detected a lack of public concern for the men and women fighting overseas. Off post, people went about their lives without a real understanding of the sacrifices made by American service members.

At first the anger boiled inside. But then it began to surface. He took it out on Heather. It was a release so that he could keep his work as normal as possible.

Little things like arranging the dishwasher became big fights with Heather. Big things like Heather’s life plans became small issues that Turner mocked or discounted because they did not fit his own plans.

"I came home angry," Turner told me. "Even my attitude, which I thought I was in control of, was walling me in. I didn't realize it until my wife told me, 'You're no longer welcome in our house.'"

During the deployment in Iraq, Turner had pined for Heather and his three young children, Elie, Sam and Meribeth. Now, he was losing them.

"The thing I was angry at was the very thing I was longing for during my deployment - my family," he said.

Heather said her husband was disengaged, impatient. She wanted them to seek counseling but Turner refused, insisting that she was the one who had issues.

Just a few months after his return from Iraq, Darren and Heather Turner separated.

“I was very selfish and tried to control my surroundings, which crushed those closest to me,” Turner said.

Turner eventually realized how much he had hurt his wife, he said. How he had stepped away from God's calling by failing those he cared about most.

After finishing Airborne School, he quit the Army in August 2009, believing the military would demand too much time away from his family at a critical juncture in their lives.

He took a job in sales at a Home Depot not far from his house in Dacula, Georgia. He struggled to mend his marriage and reconnect with his faith.

Four months later, Turner and his wife reconciled. He chose to return to the Army as a chaplain, he said, "a renewed man both in marriage and profession."

He and Heather found their calling. God, he said, gave them a special connection with soldiers and their families. They know they will stay busy for a while.

The U.S. mission in Iraq ended on December 18, 2011, as the last American soldiers climbed into hulking trucks and armored vehicles at Camp Adder, the southernmost base in Iraq.

The war, however, is sure to continue on a second front - in America's cities and homes. And in the offices of counselors and chaplains like Darren Turner.

Turner reminisces about Iraq often, and when I saw him at Fort Campbell, he told me he wrestled with mixed feelings on the day America's military presence ended. He hopes that, in the end, the war will have been worth the blood that was spilled.

Another war, the one in Afghanistan, is far from over, with casualties mounting every month. Today, Turner counsels soldiers serving there. His words, honed from experience, are more specific now.

Get Skype, he says.

Perhaps it's not what a soldier expects to hear from a man of God. It’s certainly not the stuff of Sunday sermons.

But it's practical advice that Turner knows will go a long way toward filling the emotional vacuum. He believes distance from one’s own family can trigger a breakdown, especially when a soldier is coping with injuries and combat stress.

"Being away from your family for that long is way more difficult than I anticipated," Turner said.

Skype, he discovered, is the next best thing to being at home. You can't feel someone or smell them but you can see and hear.

"That's two of the senses," he said. "That's exponential."

Turner’s pastoral passion is still driven by the force that first drew him to the chaplaincy: Jesus.

Everyone has faith in something, Turner said. His own conviction is that Jesus answers longings in the human heart and provides perspective. Beyond immediate emergencies, the larger story is one of hope.

“He's been there on the other side, and came back to tell us,” Turner said. “That's the biggest event in human history, something that maintains hope, even in battle. When soldiers get that, it changes everything.”

Turner said he may not have been God’s perfect messenger, but that his selfish choices do not negate God’s love.

Turner is thankful for that. And that he can carry on with his calling.

As I understand it, the FBI and the U.S. Attorney moved in on Wilkerson and Turner becsuae the agency received specific allegations that they had a practice of taking pay-offs. In other words, there was at least one witness willing to testify and there was evidence. Is Marc saying that there are similar witnesses and similar evidence available against DiMasi and the FBI is purposefully not pursuing the case? If so, he presents no proof of that, and it seems to me that Marc's argument boils down to this: Many politicians are crooks, but since only some of them get caught, we should blame law enforcement for not catching the ones we really don't like.
